Quantum Weyl Relations arising from Two-Term Complexes

Qinghua Chen, Yonggang Hu

Let $Q$ be a Dynkin quiver over $k = F_{q}$ , let $A = k Q$ , and let $\Ktwo(\cP)$ be the extriangulated category of two-term complexes of projective $A$ -modules. We study the squar…

One-sided n-suspended categories

Jing He, Yonggang Hu, Panyue Zhou

Let $n$ be an integer greater or equal than $3$ . We give a simultaneous generalization of $(n - 2)$ -exact categories and $n$ -angulated categories, and we call it one-sided $n$ -suspen…

s-Recollements and its localization

Yonggang Hu, Panyue Zhou

We introduce a new concept of s-recollements of extriangulated categories, which generalizes recollements of abelian categories, recollements of triangulated categories, as well as…

Torsion pairs and recollements of extriangulated categories

Jian He, Yonggang Hu, Panyue Zhou

In this article, we prove that if $(A, B, C)$ is a recollement of extriangulated categories, then torsion pairs in $A$ and $C$ can induc…

Cosilting modules arising from cotilting objects

Yonggang Hu, Panyue Zhou

Let $R$ be a ring. In this paper, we study the characterization of cosilting modules and establish a relation between cosilting modules and cotilting objects in a Grothendieck cate…

The representation invariants of 2-term silting complexes

Yonggang Hu

Let $A$ be a finite dimensional algebra over a field $k$ and $P$ be a 2-term silting complex in $K^{b} (proj A)$ . In this paper, we investigate the representation dim…
